目的:建立三九胃泰颗粒的质量标准。方法:采用TLC法鉴别方中黄芩、白芍、九里香;采用HPLC法测定黄芩苷的含量。结果:在TLC色谱中可检出黄芩、白芍、九里香的特征斑点,清晰,易于观察;黄芩苷在0.21～5.13μg范围内线性关系良好(r=1.000 0),平均回收率为99.7%,RSD=1.1%(n=6)。结论:方法简便、准确、稳定且无干扰,可作为该制剂的质量控制方法。
Objective: To establish the quality standard of Sanjiu Weitai Granules. Methods: TLC method was used to identify Radix Astragali, Radix Paeoniae Alba and Radix Angelicae Sphagnum. The content of Baicalin was determined by HPLC. RESULTS: The characteristic spots of Astragalus membranaceus, Bletilla striata, and Prunus mumeum were detected in TLC chromatogram, which was clear and easy to observe. The baicalin had a good linear relationship (r=1.000 0) in the range of 0.21 to 5.13 μg. The average recovery was 99.7%. RSD = 1.1% (n = 6). Conclusion: The method is simple, accurate, stable and non-interfering. It can be used as a quality control method for the preparation.
